Not a restaurant, more a brodje place, but therefore the best in Utrecht! Everyone always paises Broodje Mario, forget about them, they are only cheap and big.
De Blauwe Kameel has very nice bioligical bread, everything is made with care and love for food, the sandwiches and even the coffee tastes fantastic. The ambiance is nice, but more like a take out place, outside its mooi, but as we all know the dutch weatehr is not very supportive with that. But very nice service and delicious brodjes, my favorite
